Single-Course English 10 ECTS

High voltage engineering

Overall Course Objectives

The course is addressed to students who want a basic knowledge about high voltage engineering.
The teaching is directed towards an understanding of important electric phenomena, the understanding of which is necessary for correct design and construction of high voltage components and other apparatus with high electrical fields.
Lectures and experimental laboratory exercises are combined with several calculations and numerical simulations to give insight into the special test, measurement and calculation methods that are used within high voltage engineering, where high voltages and currents occur over a broad frequency range.
The students will be able to evaluate different types of insulation materials used in apparatus with high electrical field strengths and where aging phenomena due to electrical and thermal stresses are important.

Learning Objectives

  • Show the most essential criteria for dimensioning of high voltage apparatus
  • Calculate simple electric fields and important component parameters
  • Solve electrical field problems numerically
  • Explain electrical discharge phenomena and estimate their relevance for electrical insulation systems
  • Formulate principles for component breakdown and relate them to laboratory tests
  • Evaluate the electrical breakdown strength of different materials
  • Design systems for generation of ac, dc and impulse voltages
  • Choose and apply suitable equipment for measurement of high voltages and currents

Course Content

After a general introduktion to high voltage engineering will methods for the calculation and control of electric fields in electric apparatus be covered, including numeric field calculations (FEM) for correct design of insulation systems.
The basic mechanisms in connection with the electric strength of gasses, liquids and solid dielectric media are studied. Lightning and lightning protection will be treated and illustrated by means of examples. Furthermore, laboratory techniques for the generation of high voltages with the associated measurement techniques are treated.
The topics are studied in further detail under the group work and laboratory exercises.

Recommended prerequisites

Fundamental knowledge within electrical circuits and static electromagnetism.

Teaching Method

Lectures, compulsory laboratory exercises and solving of minor problems in groups.
